Getting the Wattage Right for Your Bathroom
If you’ve ever stepped out of a shower into a freezing bathroom, you know that feeling. It’s miserable. But here’s the trick: you don’t actually need to heat the whole room. Trying to warm up damp air and cold tiles is a losing battle. That’s why we use short-wave infrared. Instead of fighting the air, it beams heat directly onto you. It’s like standing in a patch of sunlight on a crisp morning.
Finding Your Sweet Spot
You can’t just grab the most powerful lamp and call it a day. If you put a massive 1200W unit in a tiny powder room, you’re going to bake. The thermostat will basically panic, clicking on and off every few seconds. We call that short-cycling, and it’s a great way to kill your filaments early. For those small spaces (under 4 square meters), stick to something in the 400W to 600W range. It’s plenty. For a medium bathroom (5-8 square meters), you’re looking at 800W to 1200W. But if you’ve got a huge master bath—anything over 10 square meters—don’t just buy one giant heater. You’ll end up with one scorching spot and three freezing corners. Instead, go with a few 600W units spread across the ceiling. It keeps the warmth even.
The “Height” Problem
Here is something most people forget: distance matters. Heat loses its punch the further it has to travel. If you have high ceilings (over 2.5 meters), you’ll need a higher wattage lamp just to make sure you actually feel the warmth by the time it hits your shoulders. And a quick heads-up on the electrics. Higher wattage means more pull on your power. If you try to run a 1500W setup on thin, old wiring, you’ll get voltage drops. It ruins the lamp’s lifespan and isn’t exactly ideal for your home’s safety. Check your breakers first.
Real-World Setup
When you’re installing these, remember that they need a clear line of sight. If you tuck a lamp behind a bulkhead or jam it right next to a loud vent fan, you’re wasting energy. The heat just won’t reach you. Also, give the unit some breathing room. Leave about 15cm between the lamp and the ceiling. It stops the heat from soaking into the structure of your house and keeps the focus exactly where it should be: on you.
